I wonder if 3D models mean that we can re-scale the objects in an editor and create world trees and King Kongs? Of course if the map consist of "tiles", rescaling may be tricky.
No, I am not asking it because it is fun, but I am still concerned about the realism in Homm world. It would be truely annoying to keep constantly missing important objects because they are too small and can unintentionally hide themselves behind anything else. WC3 is a great strategy game, but it is unrealistic in the means of object sizes. I don't believe it is a Blizzard mistake, it is because the strategy does not work otherwise.
Thus I would like to pressure once again that the developers look carefully that the realism does not reduce gaming experience or that they give some tools for modding.
